It is a left-over before I adopted b4. I'll do the cleanup.

At some in my frequent system upgrades (rolling release), it
uninstalled the yamllint

warning: python package 'yamllint' not installed, skipping

It should have catched that before.

leds are already defined for a port. I'm just trying to add a
restriction to allow only 0-3 leds and use that to identify the group.
These suggestions will redefine the leds property, forcing me to
declare #address-cells, #size-cells for leds and reference the led
schema in led@[0-3]. Is there a way to just add a constraint to what
is already present?
